Commercial Surge Protection Systems on Oahu

Facility-grade Type 1 and Type 2 SPDs for sensitive commercial equipment and tenants across Honolulu, Aiea, and beyond.

Commercial Surge Protection

Protect Every Tenant. Every Server.

Commercial surge events — from HECO grid switching, lightning, generator transfer, or internal load events — can take out servers, POS systems, HVAC controls, refrigeration, and tenant equipment in milliseconds. The replacement cost (and downtime) of even one bad surge dwarfs the cost of proper SPD installation.

Sparky and Sons installs commercial-grade surge protection systems — Type 1 service-entrance SPDs for the highest tier of protection, Type 2 panel-level SPDs for distribution panels and sub-panels, and point-of-use protection for sensitive critical equipment.

For multi-tenant buildings, we offer a layered approach: building-wide SPD at main service, tenant-level SPD on each tenant’s sub-panel. Each tenant gets a clean, surge-protected feed.

Frequently Asked Questions

How much does a commercial SPD cost?
Varies widely by service size and protection tier. A typical multi-panel commercial install ranges from a few thousand for basic Type 2 to higher for full Type 1 + 2 layered systems.
Will my insurance discount surge protection?
Some commercial insurers offer reduced premiums or deductibles for buildings with proper SPD. Document the install for your insurance file.
How often do SPDs need replacement?
Depends on event count. Indicator lights tell you when one’s spent. Visual checks every 6 months in commercial settings is a good practice.
Can SPDs prevent all damage?
No surge system is 100% — but layered protection (service + panel + point-of-use) reduces let-through voltage to safe levels for almost all commercial equipment.
